Frequently Asked Questions regarding my PDP-11 emulator

It's running UNIX Sixth Edition, a.k.a. V6.
Yes, that's the one John Lions commented in his famous book.

Q:cd does not work!

It's called chdir on V6.

Q: Backspace does not work!

You're running a (pseudo-)hardcopy teletypewriter. There ain't no such thing as backspace!
You can use # to overwrite the last character, e.g. Hello Wol#rld will be read as Hello World.
@ works in the same way deleting the whole line, e.g. Dumbass@Nice person.

Q: WHY IS EVERYTHING IN UPPER CASE?

YOU'RE RUNNING IN COMPATIBILITY MODE WITH UPPER CASE ONLY TERMINALS LIKE THE ASR-33.
TYPE STTY -LCASE TO TURN IT OFF.

Q: How do I interrupt programs / kill programs / send EOF?

DEL is the interrupt key (^C on modern *nix), Pause the quit key (^\ or ^L) and PrtScr is EOF (^D).
